Protraction
Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes. In general, motion is classified according to the anatomical plane it occurs in. ''Flexion'' and ''extension'' are examples of ''angular'' motions, in which two axes of a joint are brought closer together or moved further apart. ''Rotational'' motion may occur at other joints, for example the shoulder, and are described as ''internal'' or ''external''. Other terms, such as ''elevation'' and ''depression'', describe movement above or below the horizontal plane. Many anatomic ...

List Of Movements Of The Human Body
The list below describes such skeletal movements as normally are possible in particular joints of the human body. Other animals have different degrees of movement at their respective joints; this is because of differences in positions of muscles and because structures peculiar to the bodies of humans and other species block motions unsuited to their anatomies. Arm and shoulder Shoulder elbow The major muscles involved in retraction include the rhomboid major muscle, rhomboid minor muscle and trapezius muscle, whereas the major muscles involved in protraction include the serratus anterior and pectoralis minor muscles. Sternoclavicular and acromioclavicular joints Elbow Wrist and fingers Movements of the fingers Movements of the thumb Neck Spine Lower limb Knees Feet The muscles tibialis anterior and tibialis posterior invert the foot. Some sources also state that the triceps surae and extensor hallucis longus invert. Inversion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
